Replace a Spare part Wheel Bearing (Hub Bearing) – a defective one or if the limit of use has been already reached. Find out useful information about Wheel Bearing (Hub Bearing)

Wheel bearings have effect on rolling characteristic of wheels and, consequently, on mobility of vehicles, their equipment and so on. Hub bearing in the car is so-called rolling bearing. The bearing consists of outer and inner rings, which keep and divide rolling elements. Outside plane of the inner ring and, conversely, inner plane of the outer ring of the have tracks, on which rolling elements are moving. These elements can be of two kinds: balls and rollers. Therefore, bearing’s name comes from the shape of the rolling element.

Rollers can be needle-shaped, cylindrical, conical and other shapes. Characteristics of the bearings must meet the requirements of the design with respect to service life, capacity, environmental influences, start rolling resistance force and other possible criteria. In vehicles there are uses two types of bearings: rolling bearings and plain bearings. The number of different bearings in cars is up to several dozens. All units are equipped with bearings, which provide a perfect, reliable operation: suspension, wheels, engine and gearbox. All vehicle bearings are under a serious load. But most of all under load is hub bearing.

Loads occur during the motion, acceleration, braking, while on the bearing hub radial, axial and combined forces are acting. For this reason the bearing hub must correspond to highest standards. If the bearing failed, it is impossible to see. But you can feel and hear: noise on tight turns, difficult rotation of the wheel at the moment when the brake is released. Replacement of the bearings should be made in workshops.

If you need to replace the bearing, buy it in our store and we will deliver it to the required address in short terms. As well as other necessary parts: headlights, mirrors and axial joints.

Diagnosing wheel hubs is recommended at each brake pad change, regardless of the car mileage. There are several options for checking the part. At a speed of 10-15 kilometers per hour take a sharp turn to the left. If at this maneuver strange sound disappears, the problem is in the left wheel hub bearing. And accordingly, vice versa. For a more accurate diagnosis you need a lift or a jack. The car must be mounted, you need to start the engine and accelerate the car at fourth gear to a speed of 80 kilometers per hour. Then depress the clutch, turn off transmission and listen to determine which of the wheels is the source of strange sounds. One more effective method of diagnosis is to shake the mounted car wheel first vertically and then horizontally. Finding even a slight play, you will know that the problem is in the bearing or the steering system. The next step is to ask an assistant to press the brake pedal to the maximum, and at the same time swing the wheel vertically. If the gap disappears, you need to replace the bearing.

Repair and replacement of wheel bearing

Repair of bearings is produced extremely rarely. The optimal solution is a replacement. It is carried out every 130 000-190 000 km. In replacement operation, it is important to:

set the gap at installation of a tapered roller bearing;

not use sharp objects that may damage the structure;

setting on axle, work with the driftpin on the inner ring;

pressing the bearing in the hole, transmit the force through the driftpin to the outer ring.
